4)N10675 has outstanding resistance to hydrochloric acid at all concentrations and temperatures. It also resists sulfuric, phosphoric, formic, acetic acids and other nonoxidizing media. It has excellent resistance to pitting corrosion, stress corrosion cracking, and knife line and weld heat-affected zone attack. N10675 has greater thermal stability than N10665.
5)Alloy C-4 has outstanding high-temperature stability, and has excellent resistance to stress-corrosion cracking and oxidizing atmospheres up to 1040ºC. It has exceptional resistance to a wide variety of chemical process environments, including hot contaminated mineral acids, solvents, chlorine and chlorine contaminated media (organic and inorganic), formic and acetic acids, acetic anhydride, and seawater and brine solutions.
6)Alloy C-22 is a versatile Ni-Cr-Mo-W alloy with better comprehensive corrosion resistance performance than other Ni-Cr-Mo alloys, including Alloy C-276, Alloy C-4 and Alloy 625. Alloy C-22 has outstanding resistance to pitting, crevice corrosion and stress corrosion cracking. It has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chloride ions. It also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. So it can be used where "upset" conditions are likely to occur or in multi-purpose
plants. Alloy C-22 has exceptional resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, chlorine, hot contaminated solutions (organic and inorganic), formic and acetic acids, acetic anhydride, and seawater and brine solutions. It resists the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition.
7)Alloy S has excellent thermal stability, low thermal expansion and excellent oxidation resistance at 1093ºC. It has good high temperature and thermal fatigue strength. It retains its strength and ductility after aging at temperatures of 427 to 871ºC. Alloy S is particularly suitable for cyclical heating conditions where
components must be capable of retaining their strength, ductility and metallurgical integrity after long time exposure.
8)N06200 is a versatile corrosion resistant alloy with excellent resistance to uniform corrosion in oxidizing or reducing environments. It resists all acids,
especially hydrochloric, sulfuric and hydrofluoric acids, at wide temperature ranges, and also resists pitting corrosion, crevice corrosion and stress
corrosion cracking induced by chlorides and other halide solutions.
9)N06030 is a high chromium nickel-base alloy which has superior corrosion resistance over most other nickel and iron-base alloys in commercial phosphoric acid as well as many complex environments containing highly oxidizing acids such as nitric/hydrochloric, nitric/hydrofluoric and sulfuric acids. It resists the formation of grain boundary precipitates in the heat-affected zone, making it suitable for use in most chemical process environments in the as-welded condition.
